Below are some activities you can do over the course of the week.
You can do one or a few each day. You can also repeat activities in order to help your child to fully understand the concepts of sharing, or if your child has particularly enjoyed them.
Playing games which include sharing out cards, items etc. Ask your child to share the cards/items equally between the number of players (can be 2 or more) and initially explain that ‘sharing equally’ means everyone will have the same amount/number of items at the end. Then when playing the same game again or a different one, ask your child how s/he will know the items have been shared equally.
Possible games: card games, Snap, Dominoes.
Using everyday objects and sharing items between 2 or more people, e.g. sweets, biscuits, segments of an orange. Ask your child to share these items equally between the number of people who are going to have them, e.g. sharing 10 sweets between 2 people:
How many sweets do you have?
Can you share them equally between your sister and you? What does ‘share equally’ mean? How are you going to share them?
If your child does not know, then prompt by saying, “I wonder what will happen if you shared them out one at a time?”
Your child might have his/her own idea, so let them have a go (even if it is not right). If they share the items and they are not equal amounts, ask your child if s/he have shared the items equally. If your child says, “No,” then ask them why they are not shred equally and how s/he are going to solve the problem. Talking through a problem and coming to a solution is a great way to learn, so let your child make mistakes.
Your child might immediately say 5 and 5. Ask him/her how they know and s/he might say “5 and 5 altogether makes 10” or “Double 5 makes 10.”
Once the items have been shared equally, count/say how many items each person has or ask your child how s/he know the sweets have been shared equally. Promote the language, “We both have the same amount.”
Then use language, such as, “10 shared between 2 is 5, each person has 5.”
Share items up to 10 initially and then up to 20.
Share between more than 2 people, but make sure the amount can be shared equally between the number of people.
Share items (any items found the house or in the toy box) between toys (up to 10 items initially, then up to 20).
If you were sharing 12 marbles between 2 cuddly toys (Teddy & Dinosaur):
How many marbles do you have?
Can you share them equally between your Teddy and Dinosaur? What does ‘share equally’ mean? How are you going to share them?
Let your child share the items between the two toys and talk though any problems encountered.
Once the items have been shared equally, count/say how many items each person has or ask your child how s/he know the marbles have been shared equally. Promote the language, “They both have the same amount.”
Then use language, such as, “12 shared between 2 is 6, each person has 6.”
Then add another toy, e.g. a doll. Now ask the child to share the same 12 marbles between the 3 toys. Follow the same process as above.
Then add another toy, e.g. a cuddly dog. Now ask the child to share the same 12 marbles between the 4 toys. Follow the same process as above.
Do the same for 6 toys.
Then discuss how the number of marbles each person has is less/fewer, the more people they are being shared between.
Teddy bears’/ toys’ picnic or party. Sharing items between the number of toys invited to the party (Make sure the number chosen can have the items shared equally between them.)
You could share plates, bowls, spoons, forks, cups, hats, napkins, different amounts of food items (play food/ real food) etc.
Use the language written in the previous activity sections.
Then have the party/picnic with the toys.
Sharing board: place different numbers of items (up to 10/20) in the first box for the children to share equally between the 2 boxes below.
Items can be things found around the house, e.g. pasta shapes, buttons, raisins etc.
Questions to ask are written on the board.
Encourage your child to use the appropriate language in their explanations.
